This study aims at developing an aerobics exercise instruction software for personal use by introducing an instruction program best fit to the physical conditions of respective exerciser. The software uses the combination ...

The increasing amount of internet based television broadcasts has lead to new approachs to interactivity in TV programs. We developed a system which is able to supply the viewer of the program upon interaction with information ...

This paper pre sents and discusses a new approach to collect, organize and explore multiple digital videos on a spatial basis. We present a methodology based on direct video frame indexation to the real space represented ...

Interpersonal communication mediated by computer services supports the reinforcement and emergence of new communities brought together by leisure or work interests. This paper presents a workbench system that aims to study ...

Artists continue to search for new methods of creation of artworks. The trend to interactive multimedia installation work requires systems that allow participants to interact in subtle ways. The paper describes a number ...

The spatial properties of digital interactive multimedia are analysed and contrasted with those of pictures, and of narrative feature films and factual television. These media have developed distinctive spatial methods and ...

A novel indexing scheme for solving the problem of nearest neighbor queries in generic metric feature spaces for content-based image retrieval is proposed to break the 'dimensionality curse.' The basis for the proposed ...

We describe a system that maps the interaction between two people to control a genetic process for generating music. We start with a population of melodies encoded genetically. This population is allowed to breed every ...

We examine the problem of searching a database of three-dimensional objects (given in VRML) for objects similar to a given object. We introduce an algorithm which is both iterative and interactive. Rather than base the ...

3D volume data has been increasingly used in many appli- cations. The digital nature of the data allows easy creation, copying and distribution. However, it also allows ease of manipulation which can enable wilful or ...

Most solutions proposed to implement audio and video distribution services have been designed for specific infrastructures or have been tailored to specific application requirements, such as stream and clients types which ...

Block motion estimation is a cpu intensive task for video encoding. Many fast algorithms have been developed to solve this problem, trying to improve both block searching and block matching. Some of them reduce the image ...

The support of abstractions in authoring systems increases the efficiency of the specification of multimedia documents. Authoring based on a very low abstraction, for example script programming, is very complex and time ...

This paper presents a server-based remote walkthrough system. The client is assumed to be a thin client, like a handset or a mobile device, with no strong processor but with some embedded video chip. The server holds the ...

Multimedia middleware needs to support a wide variety of devices together with their respective data formats. This becomes increasingly relevant and difficult in a distributed environment where new devices and formats ...

Computer animated 3D models have been increasingly used in multimedia presentations because they can be viewed and manipulated directly in 3D. In this paper, we propose a database approach for this problem. Our main objective ...

Real-time audio and video conferencing has not yet been satisfactorily integrated into web-based groupware environments. Conferencing tools are at best only loosely linked to other parts of a shared working environment. ...

In recent years, virtual rality has shown all its potential in a large spectrum of applications: training, simulation, CAD, and so on. Although existing technologies allow the creation of immersive virtual reality browsing ...

Storytelling -- a fundamental mode of human communication -- has adapted in form, content, and technique as new expressive technologies have appeared and evolved. The past century has witnessed the growth of storytelling ...

With the emergence of open information spaces such as digital libraries, advanced techniques for interactive visualization of complex and protected 3D documents are needed. This paper presents a new visualization concept ...
